A1C Test for Diabetes

Submitted by Medical Health Test Team on November 28, 2019

An A1C test is used to determine a person’s average blood sugar levels during the course of a three month period. Your doctor uses the test to determine if you are prediabetic or type 2 diabetic.

If the test indicates that you are pre diabetic, your doctor may modify your diet to include less carb intensive foods such as bread, pasta, rice and sugar. When you eat these foods they covert quickly in your bloodstream to glucose.

5.7 is a normal A1C reading, If you are 6.4 you may have prediabetes. Those with a level of 6.5 or higher definitely have diabetes. The longer your A1C stays high, the greater your risk of developing diabetes. Once diabetes has developed lowering your A1C is critical to avoid serious health issues.

The goal for most people with diabetes is 7% or less. However, your personal goal will depend on many things such as your age and any other medical conditions. Work with your doctor to set your own individual A1C goal.

Glucose, also known as blood sugar, builds up quickly in your system if you are eating high carb foods. Reducing your intake of these high carb foods, together with exercise, can decrease the level of your blood sugar if you are found to be prediatetic.

If the test indicates that you are diabetic, your doctor will start you on a treatment regimen that may include oral and injectable medications. He or she will also modify your diet to include low carb foods and exercise.

This test is key to managing your diabetes. If your Higher A1C levels continue to be high, you will be at risk for diabetes complications. Therefore it is very important to get your blood sugar under control to remain healthy.

A1c test tells you your average levels higher than normal, a fasting blood glucose test is needed to confirm a diabetes diagnosis.

When your blood contains sugar, the glucose attaches to hemoglobin in your red blood cells. While people always have sugar attached to their hemoglobin, high levels of sugar create a dangerous condition in which your blood cells are coated with this sugar.

You should have an A1C test two to three times each year. Communicate with your doctor to see what is right for you.

Research shows that having a tight control on your blood glucose will help reduce the complications of diabetes which include high blood pressure, cholesterol and heart disease.
